"is produced by passage of air through a volatile liquid hydrocarbon are already known.

For illuminating purposes the utilization of these appliances presents certain defects. Either theproduction of the gas is not regular, which results in producing at the burners supplied by the service-pipe an unsteady flame, or apparatus cannot be charged While operative, which gives rise to stoppages. The apparatus hereinafter described completely obviates these defects. It may be charged while operative, and its arrangement insures uniformity in the production of the gas.

In the accompanying drawings a carbureter, which forms the subject of this invention, is represented by way of example.

Figure 1 is a longitudinal section of the apparatus. Fig. 2 is a vertical transverse section taken on line 2 2 of Fig. l; and Fig. 3is a vertical transverse section taken on line 3 3, Fig. 1.

The apparatus consists, broadly, of a cylinder a, closed at its two extremities and divided into three compartments 6 c d by two The only communications which these three compartments present one with the other or with the atmosphere are those hereinafter described. In addition to the compartment 6, which is the largest, and the compartment d both communicate by means of two tubes f g with a reservoir 6, arranged above the cylinder. This upper reservoir e serves to contain the hydrocarbon, coming from a second reservoir or even from the cask in which it has been transported (not represented in the-drawings) communicating with the reservoir 6 by a nozzle, which may be closed by a cock h.

The tubes f g, which proceed from the top I of the compartments 1) and (Z, traverse the reservoir a and open into its upper portion. A conduit a, closed by a cock 1', also places the Serial No. 164,112. (No model.)

'reservoir 6 in communication with the compartment d. This conduit, which starts against the lower wall of e, terminates in the compartment d in an orifice obturated by avalve is, acting in combination with a float Z. An en- Velop of metallic tissue or filtering material surrounds in the reservoir 0 the aperture of the conduit 6 and arrests all foreign bodies which may be contained in the liquid hydrocarbon. I

The compartment 6 is traversed by a longitudinal shaft 19, around "which are wound four coils or conduits 1 2.3 4, the convolutions of which are arranged side by side in; three superposed rows. These coils participate in the movement of rotation upon itself,'which may be given to the shaft 10 by a motor of any suit- ,able kind by means of a belt and of a pulley fast upon the said shaft.

- I At the left-hand extremity of the apparatus, Fig. 1, the four coils 1, 2, 3, and 4 are open in the chamber 6.. These apertures q g g" g are diametrically opposite. If we assume for a moment that the chamber 6 contains liquid hydrocarbon up to a certain level, it will be apparent that the apertures q q q" q will alternately come, owing to their rotation with the shaftp, either in contact with the liquid or in contact with the air situated above it, which air enters the compartment 6 through the admission-socket a. Each coil will therefore take up alternately a certain quantity of liquid hydrocarbon and a certain quantity of air. These fluid and liquid beads or sections will travel in the coils, first of all in the outer row from left to right, owing to the inclination of the convolutions, then from right to left in the intermediate row 1 2 3 4', the convolutions of which are inclined in the inverse direction, and finally in the central row 1 2 '3 4" from left to right again. The

fluid and liquid beads, the pressure of which increases in proportion as they proceed in the apparatus, finally enter the tubular socket '1), which communicates-with-the compartment 0.

When the apparatus is started, the level y is assured in the compartments 6 and d by opening the cock j of the conduit 2', the hydrocarbon of the reservoir 6 finding an outlet at the lower part of the conduit c', since the drocarbon which rises in the compartment b causes the valve is to obturate the orifice of the conduit 71 when the hydrocarbon reaches the level'm y-in b and in d. The provision of hydrocarbon contained in. thereservoir e is then completed by opening the cock h, which places the said reservoir in communication with the vessel, (not shown,) butin having care that the level of the hydrocarbon which ment 0..

may be checked by means of a level 5 does not reach theupperpart of the tubes f g,

these tubes only serving to insure equality of pressure in the compartments Z2 and d and the reservoirs. The cockla is then closed and the shaft 19 caused to rotate. The coils rotate in the direction indicated by the arrow 6. Each of the apertures q q" q" q' enters thehydrocarbonin turn, then effects a half-revolution in-the air contained in the compartment. 6, whereupon it is again immersed in the hydrocarbon, as explained above.

The carbureted air under pressure, the recondensed vapors, and the unvolatilized hydrocarbon after having traversed the coils enter the compartment 0 through thehollow portion oof the shaft p. The carbureted air proceeds to the utilization appliances through the conduitz, while the unvolatilized hydrocarbon falls upon an inclined plane a and thence slides to the bottom of the compart- When this hydrocarbon attains a certain height, it lifts the floatt of a lever articulated at t", controlling. a valve t, and under the influence of. the pressure obtaining in the chamber 0 returns to the chamber '6.

Thehydrocarbon contained in the chambers b'and al is gradually consumed as the carbureted. air isproduced. Nowthe pressure of the gas. in the chamber'c depends upon the uid should be maintained constant, and this is produced by the fl'oat'Z. As soon as the level falls the valve .70. opens andacertain quantity of hydrocarbon coming from the reservoir 6 replaces the hydrocarbon consumed. adapted for illuminating. purposes or for motive power. is therefore contained in the chamher '0 at a constanthpressure; This-gas may be employeddirectlyif the pressure is suitable. If this is not so, it may be passed through a pressure=reduce1n The hollow portion o of the shaft 0 rotates in a journal I o supported by. the partition separating the chambers b and 0. In this journal is formed an annular. space 7;, which Gas 7 the lubricating -oil enters through the pipe o'. A ring '0 acting as astufiingsbox, prevents any possibility of anescapeofgas from the chamber 0 into the chamber 6.
